Containing the leaks on Lost

TV Squad points to an enlightening and revealing New York Times article concerning plot leaks on Lost. Producers are interviewed and some of the machinations of secret-keeping, though no “spoilers”, are revealed.

Obligatory article blockquote for those that don’t do the whole registration or Bug Me Not thing:

Damon Lindelof and Carlton Cuse, two executive producers of “Lost,” said they have no idea how the purveyors of spoilers get information about their series. They have put in place a numerical coding system to keep track of scripts, but it doesn’t seem to fix the problem. At the end of last season, when the writers were determined to keep a kidnapping in the finale a secret, they were driven to extremes. Internally, the scene was referred to only by a prosaic nickname: “the bagel.” And only the actors in that particular scene received script pages.
